Clockwork Olive: multicast update

After much pissing around it turns out multicast does work, but emcast has been having problems. Dbeacon runs well in super verbose mode, emcast receives the info, but just doesn't seem to send very well - it could be that the olives are just being shit and dropping packets though.

Want to see the config?


interfaces {
    em0 {
        unit 0 {
            family inet {
                address 192.168.2.2/24;
            }
        }
    }
    em1 {
        unit 0 {
            family inet {
                address 192.168.12.1/24;
            }
        }
    }
    gre {
        unit 0 {
            tunnel {
                source 192.168.12.1;
                destination 192.168.12.2;
            }
            family inet {
                address 192.168.102.1/30;
            }
        }
    }
    ipip {
        unit 0 {
            tunnel {
                source 192.168.2.2;
                destination 192.168.2.1;
            }
            family inet {
                address 192.168.201.2/30;
            }
        }
    }
    lo0 {
        unit 0 {
            family inet {
                address 1.1.1.2/32;
            }
        }
    }
}
routing-options {
    interface-routes {
        rib-group inet if-rib;
    }
    rib-groups {
        multicast-rpf-rib {
            export-rib inet.2;
            import-rib inet.2;
        }
        if-rib {
            import-rib [ inet.2 inet.0 ];
        }
    }
    autonomous-system 65001;
}
protocols {
    igmp {
        interface all {
            version 3;
        }
    }
    bgp {
        local-as 65001;
        group olive {
            type external;
            family inet {
                any;
            }
            export to-branch1;
            peer-as 65000;
            neighbor 192.168.201.1;
        }
    }
    msdp {
        rib-group inet multicast-rpf-rib;
        group test {
            peer 192.168.201.1 {
                local-address 192.168.201.2;
            }
        }
    }
    pim {
        rib-group inet multicast-rpf-rib;
        rp {
            local {
                address 192.168.102.1;
                group-ranges {
                    224.0.0.0/4;
                }
            }
        }
        interface all {
            mode sparse;
            version 2;
        }
        dr-election-on-p2p;
    }
}
policy-options {
    policy-statement allow-all {
        then accept;
    }
    policy-statement to-branch1 {
        from protocol [ direct local ospf bgp pim ];
        then accept;
    }
}


I'm going to be a bastard any sources except this one. I'm tempted to chalk the emcast send failure down to packets simply being dropped, and maybe try a test VLC stream if I can be bothered with that, but this was only meant to be a means to an end - the next step is IPv6 multicast!
